    1. CO@JBNizet I must appologise I was getting very upset at you. My code seemed to be happily adding in TreeMap objects as keys, so I didn't believe you! So I modified my above code, ran the test... and I can o announce my code was seriously flawed somewhere down the line. I now need a better 'sorting' solution to my legacy DB data mining. I need to offer you a big thankyou, otherwise I may have been chasing this for a long time and it wouldn't have caused me problems untill later on. So back to using hashMaps for some stuff and sending the data into an SQLite / DerbyDB before playing with it!

    2. CO@JBNizet OK I just tested it. My actual code is obviously printing out info before it gets put into the TreeMap, so it looks like the treeMap is getting the data when in fact it isn't. Back to using unordered HashMaps, or subClassing TreeMap.

    3. CO@JBNizet The doc states that TreMap.put(k,v) Throws: ClassCastException - if the specified key cannot be compared with the keys currently in the map. So if TreeMap doesn't implement both comparable and hashcode somewhere in its inheritence I wouldn't be able to use one as a key without throwing an error (which doesn't happen). That is probably a better description of my question. TreeMap is apparently not comparable, so I shouldn't be able to use one as a key in my TreeMap.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
